Hibiscus plant named ‘Lanlampasas’

ABSTRACT

A new cultivar of  Hibiscus  named ‘Lanlampasas’, characterized by its very large flowers that have red centers and wide golden orange margins, its short leaf internode lengths, its very dark green foliage, its good self-branching, and its very vigorous growth habit.

Botanical classification: Hibiscus rosa-sinensis.

Cultivar designation: ‘Lanlampasas’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus plant of hybrid origin, botanically known as Hibiscus rosa-sinensis ‘Lanlampasas’ and will be referred to hereafter by its cultivar name, ‘Lanlampasas’. ‘Lanlampasas’ is a new cultivar of tropical hibiscus grown for use as a landscape and container plant.

The new cultivar was developed through an on-going breeding program conducted by the Inventor in Malause, France. The objectives of the breeding program are to develop new cultivars of Hibiscus that exhibit compact plant habits with self-branching and a well-balanced plant habit.

The Inventor made a cross in July of 2006 between ‘Adele’ (not patented) as the female parent and ‘Soleil Ambre’ (not patented) as the male parent. ‘Lanlampasas’ was selected as a single unique plant from the resulting seedlings in September of 2009.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in Malause, France in September of 2009 by the Inventor. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics ‘Lanlampasas’. These attributes in combination distinguish ‘Lanlampasas’ as a new and distinct cultivar of Hibiscus.

-   -   1. ‘Lanlampasas’ exhibits very large flowers that have red         centers and wide golden orange margins.     -   2. ‘Lanlampasas’ exhibits short leaf internode lengths.     -   3. ‘Lanlampasas’ exhibits very dark green foliage.     -   4. ‘Lanlampasas’ exhibits good self-branching.     -   5. ‘Lanlampasas’ exhibits a very vigorous growth habit.

Both the female parent of ‘Lanlampasas’, ‘Adele’, and the male parent, ‘Soleil Ambre’, differ from ‘Lanlampasas’ in having smaller flowers with very little red coloration and in having stems with less self-branching. In addition, ‘Adele’ has a less vigorous growth habit. ‘Lanlampasas’ can also be most closely compared to the cultivars ‘Apollo’ (U.S. Plant Pat. No. 23,072) and ‘Madrid’ (not patented). Both are similar to ‘Lanlampasas’ in having flowers that are orange in color with red centers. ‘Apollo’ differs from ‘Lanlampasas’ in having much smaller flowers with centers that are lighter red in color with pink stripes from the base to the margins of the petals and in having longer leaf internodes. ‘Madrid’ differs from ‘Lanlampasas’ in having smaller flowers with a very small red center (mostly orange) and in having a less vigorous growth habit.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Hibiscus. The photographs were taken of a six month-old plant of ‘Lanlampasas’ as grown in a one-gallon container in a greenhouse in Malause, France.

The photograph in FIG. 1 provides a side view of ‘Lanlampasas’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘Lanlampasas’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Hibiscus.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 8 month-old plants of the new cultivar as grown in two-quart containers in a greenhouse in Grand Saline, Tex. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
